Check The Control Directions
1. Turn on t h e T r a n s m i t t e r and then the Receiver.
S t a n d i n g behind the plane, make the following
movements with the transmitter and observe the
control surfaces:
4-CHANNEL RADIO SET-UP
(STANDARD MODE 2)
If any of the servo movements are opposite, reverse
the servo direction with the servo reversing switches
on the transmitter.
Adjust The Throttle
2. For added safety and convenience, the throttle
should be set up so that the engine can be stopped
using the throttle trim. To do this, loosen the pushrod
connector screw and move the throttle pushrod so
that the carburetor is completely closed with the
throttle stick and trim lever on the transmitter fully
back. (NOTE: If the carburetor does not fully close,
adjust the idle stop screw on the carburetor until it
will.) N e x t , t i g h t e n the screw on the pushrod
connector. Test the trim lever by advancing it to full.
This will be a fast idle position
w i t h the c a r b u r e t o r barrel
slightly open ( a b o u t 1/32").
See sketch. Now move the
throttle stick forward to full.
Make sure that the carburetor
barrel opens all the way. See
sketch. If it doesn't open far
e n o u g h or opens too far
( b e n d i n g the rod) move the
pushrod connector in or out
on the servo arm a n d / o r the
c a r b u r e t o r arm to gain or

connector. The throw w i l l be correct when the
carburetor barrel will stop fully open at the same time
the throttle stick reaches full. With the throttle set up
properly, you should be able to run the engine with
the trim lever set midway to full position (adjusted for
a smooth but slow idle). Then when it is time to stop
the engine, simply pull back the trim to close the
carburetor and the engine will stop running.
Adjust the control throws:
3. Check the movement of the control surfaces. Use a
ruler to match our measurements listed below. If your
radio features dual rates, set up both the high and the
low rates following the radio system's instructions. If
your radio does not have
dual rates, set up the plane
u s i n g the low rates first
and increase the throws as.
you get familiar with the
plane.
Low rate
Aileron:
3/16" up
3/16" down
1/4" up
Elevator:
1/4" down
Rudder:
5/8" left
5/8" right
These are the suggested deflections from center.
If you need more movement, you should move the
clevis to a hole closer to the surface or you can install
a larger servo wheel and move the rod further out
from center. If you have too much movement, do
the opposite. See sketches below:
Moving the clevis outward on the servo arm results in more
pushrod movement.
Moving the clevis inward on the control horn results in more throw.
